How do vaginas work?

I have never been penetrated or anything with that area. My boyfriend and I were playing around and he was looking and he said something didn't seem right, like there was a bone or something over the hole. Any ideas as to what could be wrong?

If you've never been penetrated by anything, it's more than likely the hymen. Hymens come in all shapes and sizes, and can seem very strange looking if you've never seen one before. Here's a link for more information about hymens and even some drawings of a few different types of hymens.

Because with feeling, he might just be feeling the pubic bone, which is indeed located in the area. Anatomical Drawing.

The drawing makes it look far apart, but it's pretty typical, I think, to be able to feel it even when entering the vagina. A lot of people talk about getting toys like the Ella "hooked" on it - to give you an idea of the shape.

Depending on the position you were in while he was playing with you, it could've been your hymen or your pubic bone, in certain positions the pubic bone will close off your vaginal opening a bit more. I definitely notice this when changing positions without pulling out during sex, leaning certain ways will feel super uncomfortable because of the pubic bone. Has he ever been with a female before, as in, does he know what a healthy vagina looks like?
Have you ever penetrated yourself with your fingers? If so, did it feel tight? You might have a microperforated hymen, or sometimes females are born with vaginas that are too tight for normal penetration, or if it feels like a lump, it could be a cyst. I'm assuming you haven't had a pelvic exam before? It might be a good idea to go get checked out if something seems abnormal.

Sounds like your pelvic bone. If you are concerned about it make an appointment with an OB GYN. And talk to them about it. However, it sounds completely normal. All vaginas are shaped different. I can feel my pelvic bone. I have to be careful what toys I use because of my pelvic bone. You might be the same.
